CAR-COUPLING.

SPECIFICATION forming part of Letters Patent N'o.'376,244, dated January10, 1888.

Application filed October 11, 1887. Serial No. 252,009. (No model.)

fl?) all whom it may concern.-

Be it known that I, JONATHAN HENDER- SHOT, of Evelyn, in the county ofWirt and State of \Vest Virginia, have invented a new and usefulImprovement in Oar-Couplings, of which the following is a full, clear,and exact I description.

.in which similar letters of reference indicate corresponding parts inthe several views.

Figure 1 is a longitudinal sectional view of a draw-head having myimproved car-coupling applied thereto, showing the position of thelatter when ready for coupling with an opposing draw-head. Fig. 2 isasimilar view of the same, showing the position of my improvedcar-coupling; when coupled to the link of an opposing draw-head. Fig. 3is a vertical sectional view of the same and an end elevation of the carplatform, and Fig. 4 is a plan view of the same.

The draw-head A is provided with the usual opening, B, to receive thecoupling-link O.

In the center of the top of the draw-head is formed a longitudinalgroove, D, in which is pivoted, at e, a lever or other swinging member,E, having formed on its free end adownwardly-projecting lug, F, which isadapted to pass through a slot, G, in the bottom of the groove D. Theend of the lug F enters a recess, D in the bottom of the link-opening B,so that the strain of the coupled link on said lug will not be entirelyborne by the pivot of the swinging member, but will be transmitteddirectly to the draw-head.

A block, H, held within the groove D, is adapted to slide back and forthover the swinging member, and to the top of said block the draw-head,the opposite end of said lever being pivoted to a link, L, which ispivoted to a bar, M, adapted to slide transversely beneath the platformof the car, said bar being provided at each end with a handle, N.

The side edges of the block H are beveled at the top, and plates 0,secured to the top of the draw-head and over the beveled edges of thesliding block; serve to hold and guide said block in the groove 1). Apowerful spring, P, is interposed between the rear end of the block Hand a cross-piece, Q, on the top of the draw-head, and acts to throwsaid block forward, as hereinafter explained. The swinging member E hasformed atits rear extremity an upwardly-projectinglug, B, thetop ofwhichhas a slight bevel, so that when the lugF rests in the recess at thebottom of the draw-head opening the lug R will project slightly abovethe bottom of the groove in which the block. slides, as shown in Figs. 1and 2 of the draw lngs.

The sliding bar M is connected by a link, S, to a handlelever, T,pivoted in the platform U of the car and projecting upward, as shown inFig. 3 of the drawings. To the top of the draw-head, at its outer end,is secured acrossplat'e, V, under which the sliding block rests yvhenthe car is coupled.

The operation of my improved car-coupling is as follows: When the carsare uncoupled, the sliding block is atthe rearend of the drawhead, andis held in place by the lug at the rear end of the swinging member, asshown in Fig. 1 of the drawings. The entering link strikes against thefront edge of the lug at the front end of the swinging member and forcessaid lug upward until the link passes inward,

when said lug drops into the link and enters the recess in the bottom ofthe draw-head. As said lug is forced upward the lug at the rear end ofthe swinging member is carried downward sufficiently to release thesliding block, which is then forced forward by the spring to the frontend of the draw-head over the lug at the front end of the swingingmember, and is held securely between said lug and the crossplate on thetop of the draw-head, as shown in Fig. 2 of the drawings, thuspreventing the strain on the lug from forcing it upward and uncouplingthe cars. The sliding block is carried to the rear to permit ofuncoupling the cars by moving the sliding bar in the direction of itslength by means of the handles on said bar or the handle-lever connectedto said bar.

Having thus fnllydeseribed my invention, what I claim as new, and desireto secure by Letters Patent, is

1. In a car-coupling, the combination, with a draw-head, A, having alongitudinal groove, D, in its top, of a block, H, adapted to slideiusaid groove, an elbow-lever, J, pivoted at its angle to a lateral arm,K, on said draw-head and pivotally connected to said block, a bar, M,adapted to slide transversely beneath the car-platform and connected tosaid lever by a link, L, a handle-lever, T, connected by a link, S, tosaid bar, and a spring, P, interposed between said block and across-piece, Q, on said drawhead, substantially as shown and described,for the purpose herein set forth.

2. In a car-coupling, the combination, with a draw-head, A,havingalongitudinal groove, D, in its top, of aswinging member, E,pivoted in said groove, a block, H, adapted to slide transverselybeneath the car-platform and. provided with a handle, N, at each end, anelbow-lever, J, pivoted at its angle to a lateral arm, K, on saiddraw-head, one arm of said lever being pivotally connected to saidblock, and alink, L, connecting the other arm of said lever to saidsliding bar, substantially as shown and described, for the purposeherein set forth.

3. In a car-coupling, the combination, with a draw-head, A, havingaiougitudinalgroove, D, in its top, of a block, H, adapted to slide insaid groove, an elbow-lever, J, pivoted at its angle to a lateral arm,K, on said drawhead, a bar, M, adapted to slide transversely 4o beneaththe car-platform, a link, L, connecting said lever and bar, and ahandle-lever, T, piv oted in the car-platform and connected by a link,L, to said bar, substantially as shown and described, for the purposeherein set forth.

4. In a car-coupling, the combination, with a draw-head, A, havingalongitudinalgroove, D, in its top, of a swinging member, E, pivoted insaid groove and provided at its outer end with a downwardly-projectingcouplinglug, F, a block, H, adapted to slide in said groove, means,substantially as shown and described, for moving said block, and acrossplate, V, on top of the draw-head at its front end, substantiallyas shown and described, for the purposeherein set forth.

5. In a carcoupling, the combination, with a draw-head, A, having alongitudinal groove, D, in its top, and a recess, D, in the bottom ofits link-opening B, of a swinging member, 15, pivoted in said groove andprovided with a downwardly-projecting coupling-lug, F, at its outer endadapted to enter said recess, a block, H, adapted to slide in saidgroove, and means for shifting and securing said block, substantially asshown and described, for the purpose herein set forth.

6. In a car-coupling, the combination, with a draw-head, A, having alongitudinal groove, D, in its top, and a recess, D, in the bottom ofits link-opening B, of a swinging member, E, pivoted in said groove andprovided with a downwardly-projecting coupling-lug, F, at its outer endadapted to enter said recess, and an upwardly-projecting stop1ug, R, atits inner end, abloclz, H, adapted to slide in said groove and to beengaged by said stop-lug, and means forshifting and securing said block,substantially as shown and described, for the purposes herein set forth.
